To all whom #may-concern.' n

Be it known that I, BURR B. -BLOOD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed Construction, of which the following is a specification.

My invention relates to devices for yieldingly supporting a'bed bottom on a bedstead frame.

Broadly considered, the object o f my'invention, generally stated, is to provide a novel and etiicient construction* of cushion'- ing device for removablyand yieldingly supporting a bed bottom on the side vrails of the bedstead frame.

More specifically considered, the'object of my invention is to provide a device .ofthis kind that can be 'readily applied to bed bottoms of ordinary and approved form, without kmaterially -changing the construction thereof,and without requiring the use of special castings or other parts for the bed bottom frame.

To these and otheruseful ends myv invention consists in matters hereinafter set forthl and claimed.

My invention, in one` form thereof," is illustrated in the accompanying drawings, in whichi Figure l is a perspective elevation of the Vcomplete bed construction; and Fig.Y 2 is a fragmentary detail, enlarged, of the corner portion of the bed-bottom Vframe'anol its spring supporting device;'Fig. 3 is a trans-Y verse section through the bed on line in Fig. l.` z

Referring to the drawing, l and 2 designate, respectively, the head and foot pieces, and 3 the side rails of an ordinary metallic bedstead. f r x 4 designates cross-bars extending between and resting at their ends upon the side rails 3 adjacent to the lupper andl lower ends of the latter.

5 designates as a whole the` bed-bottom, the frame of which comprises essentially transverse endV bars 6, preferablymade of angle-iron, longitudinal side bars 7, herein Yshown as tubular in form, and vertically disposed corner bracketsl 8 connecting said side and end bars.

springs.

9 designates the bed-bottoni fabric'whi'ch is stretched between the end bars 6, as usual. l() designates coil compression springs, which are stepped upon the cross-bars L just inwardly of the outer ends 'of the latter. Through thesesprings extend tension bolts 1l, said bolts also extending through yregistering holes in the tubular side bars 7 'and cross-bars 4.' The head of each bolt engages a washer 12 restingk upon the upper end of the spring; and the'lower end of :the

bolt, which'projects below the side bar 7,- ,v

' i' 6'5 Byrreason of the foregoing constructionV is threaded' to receive a 'wing-nut 13.

it will readily be seen that the weight of the bed-bottom and of whateverload it may ratei/ieee nov. 30,1915. Y

jat

carry is transn'iit'ted to the side rails 3 of'.Y

fth'e bedsteadframe through the nuts 13,

boltsll, washersjlQ., springs l0, and crossbars 4, the boltsrll being under tension, and:V rthe springs'lO/under compression. It will also'bevnoted that by turning the nuts' 13 up or down,'the springs l0 can be regulated or adjusted to give the vdesired cushioning effect. It will 'be still further notedfthat the vdescribed v'construction does not require any special form orv construction of corner bracket, "but isapplicable to any construction of bed-'bottomframe wherein the end andV sidel bars of the frame 'are so connected that the latterare sufficiently" lower than the former to 'accommodate'.tlie cushioning An y'mportvant consideration of my inven- `tioii,.it will be seen,y isthe fact that with this construction eachV bolt or rod l1 becomes Ia supporting element, as it receives the weight yas a'tensil `.strain thereon, communicated to the lower end thereof by the side bar 7,

lwhereby the bed-bottom frame ishung in positionk on the springs.y In this way,'said bolts or other supporting elements ll are essentialr for sustaining' the weight of the bed-bottom, as well as for guiding purposes, beinggadapted to perform this combined function in a simple and efcieiit manner. This, it will be seen, is advantageous, as previously explained, and as will be Vreadily Yap'preciatedvby :those skilled in the art.

From the foregoing it will be seen that the fourfsupporting bolts 11 transmit all of which the weight can becommunicated to v said springs., Furthermore, and by means held at their lower ends.

ofthe bed bottomV frame, the "lower ends of said bolts are maintained in iXed relation to each other, whereby their lower ends do not move toward or away from each other, while the springs are in action. At the same time, however, the upper ends of said bolts may yield slightly, in a lateral or horizontal direction, and to an extent depending upon the stiffness of the bolts and the degree of firmness or rigidity with which they vare Therefore, and withthe bolts secured only at their lower ends, a slightyielding action is possible at their upper ends, if necessary, thus preventing the binding action whichrmight resultA if the upper ends of the bolts were rigidly and positively held against lateral movement. Y

The form of my invention herein disclosed has some advantages, and may be preferable in some cases,'but for the broader purposes o f my invention I do not limit myself to the exact construction shown and described.

I claim- 1. In a bed construction, a bed bottom frame, bolts for supporting said frame, disposed vertically at the sides thereof, means provided with portions forming guides in which said bolts move upA and down, said means beingrarranged for supporting the.

bed bottom on the side rails of a bedstead and being removable upwardly with the bed bottom from the rails, and springs resting on Vsaid means and carried thereby on said bed bottom frame and connected to eX- ert their tension upwardly on said bolts to Y yieldingly support thebed bottom, said bolts transmitting all of the weight sustained by ,said springs. Y v Y 2.In a bed construction, a bedstead frame, a bed bottom frame, bolts forsup- Vporting. said bed bottom frame, disposed vertically at the Ysides thereof, means resting`on the sides of said bedsteadv frame,

Vprovided with portions forming guides in 50 Vwhich said bolts move up and down, for supporting the b ed bottom on the side rails of the bedstead,and removable upwardly with the bed bottom from the rails, and springs resting on said means, and carried thereby on said bed bottom frame, and con- "nected to exert their tension upwardly on said bolts serving to yieldingly support the bed bottom, said .bolts transmitting all of the weight sustained by said springs, and said means having Vprovisions vwhereby the guides at Aopposite sides of the bed are held in position a iiXed distance apart.

3. In a bed constructioma bedstead frame,

:a bed bottom frame, bolts `for supporting ksaid bed bottom frame, disposed vertically at the sides thereof, means resting on said bedstead frame, provided Vwith portions forming guides in which said bolts move up and down, for supporting the bed bottom v on the side rails of the bedstead, and remov# f able upwardly vwith the bed bottom from ,the rails, and springs resting on said means,

In a bed construction,abedstead frame, a bed bottom frame, bolts for supporting said bed bottom frame, disposed vertically at the sides thereof, means resting on said bedstead frame, provided with portions forming guides in which said .bolts move up and down, for supporting the bed bottom on the sidek rails of the bedstead, and removable upwardly with the bed bottom from the rails, and springs resting on said means, andv carried thereby on said bed bottom frame, and connected to exert their tension upwardly on said bolts, serving to yieldingly support the bed bottom, said bolts transmitting all of the weight sustained by said springs, andsaid frame having corner castings, together with means entirely independent of said Vcastings for securing the lowerk ends of the bolts to the sides of thev bed bottom. y y n 5. In a bed construction, a bed bottom frame, bolts for said frame, disposed verticallyat thesides thereof, supporting members providing guides in which said bolts move up and down, for supporting the bed bottom on the side rails of a bedstead, removable'upwardly with the bed bottom from the rails, springs combined with said bolts,
